Abstract

The interaction of hydrogen isotope atoms with plasma facing components has an important role in the fuel recycling of future thermonuclear fusion reactors. The present paper summarizes earlier works that have been conducted to study trapping and release of hydrogen isotopes in nickel preimplanted with helium. Thermal desorption measurement was analyzed by the computer simulation code DIFFER to evaluate the trapping characteristics, i.e. the effective trapping energy and trapping efficiency. Emphasis is placed on the effect of helium content and post-implantation annealing on the trapping behaviour. The mechanism responsible for trapping of hydrogen isotope atoms at or near helium bubbles is discussed.
